Blackburn BC46-BB – Frequently Asked Questions
1) What wire sizes does the Blackburn BC46-BB C-tap take on the run and the tap?
The BC46-BB is sized for a No. 6 to No. 4 main run with a No. 6 to No. 6 tap. It is a compression C-crimp connector, so both conductors sit in the C body and are crimped in one shot with the matching die.
2) Can I use a Blackburn BC46-BB C-tap on aluminum conductors?
No. The BC46-BB is a copper connector intended for copper conductors. For aluminum or copper-to-aluminum taps you need a connector rated AL9CU or equivalent dual-rated hardware, not this one.
3) I found part number 7TAA269830R0012 on a quote. Is that the same thing as a Blackburn BC46-BB?
Yes, 7TAA269830R0012 is the current replacement identifier for the Blackburn BC46-BB C-tap. If a distributor or a takeoff sheet lists either number, you are looking at the same copper compression tap for a No. 6 to No. 4 run and a No. 6 tap.
4) Can I use the BC46-BB to tap a No. 2 feeder?
No. The run side tops out at No. 4. A No. 2 conductor will not seat properly in this C body, and an over-sized conductor forced into a compression tap will not make a listed crimp. Step up to a C-tap whose published run range covers No. 2.
5) What is the difference between a C-tap like the BC46-BB and a split bolt for a No. 6 tap?
A C-tap is a permanent compression connection: the copper C body is crimped around both conductors with a hydraulic or battery tool and the dies matched to the connector, then taped or covered. A split bolt is mechanical, reusable, and torqued with a wrench. Crews pick the C-tap where they want a low-profile, tamper-free joint and already have the crimp tool on the truck; the split bolt where they need to break the connection later or have no press. The BC46-BB handles a No. 6 to No. 4 run with a No. 6 tap.
6) Does the BC46-BB come insulated, or do I have to cover it?
It is a bare copper compression tap. The crimp has to be insulated after it is made, typically with tape or a purpose-made insulating cover sized for the connector, so plan that material into the job.
7) Are Blackburn BC46-BB C-taps sold individually or by the box?
They are sold each, so you can order the exact count the job calls for rather than a fixed carton. They are made in the United States.
8) Is the BC46-BB suitable for a grounding or bonding tap?
It is a copper compression tap connector for copper conductors within a No. 6 to No. 4 run and No. 6 tap range. For grounding and bonding specifically, the installation has to use a connector listed for that use and for the environment (direct burial or concrete encasement have their own listings), so verify the application listing matches before you crimp.
